Bonjour quelqu’un peut m’aider svp

bonjour

f (x) =  0.5 x - 2

f ( - 8) =  - 8 * 0.5 - 2 = - 4 - 2 = - 6

f ( - 3) = - 3 * 0.5 - 2 = - 1.5 - 2 = - 3.5

f ( 2)  = 2 * 0.5 - 2 = 1  - 2 = - 1

f ( 5) =  5 *0.5 - 2 = 2.5 - 2 = 0.5

5 )   f  ( - 2) = 3

g ( 4) = - 5

( h 3) = - 5

f (0) = - 1

h ( - 3 ) = - 4  et h ( 4) = - 4

h ( 2 ) = 5  et h ( - 3) = 5

g ( - 1 ) = - 2
